JK 250C Series 210L Vacuum Drying Oven is CE Certified. A 50-500ml flow meter is installed in the front panel for user to simply control and create a gas environment in the chamber.

The Vacuum Oven adopts heat radiant wall system providing optimal uniformity and conserves chamber space for drying, curing, vacuum embedding, and plating applications. 

.

Part 1 Features of Vacuum Drying Oven:
1. Radiant warm wall heating system provides optimal uniformity and conserves chamber space for drying, curing, vacuum embedding, and plating applications;
2. 3" (7.6 cm) glass wool insulation prevents heat loss from working chamber;
3. Silicone door gasket and positive latch door maintain seal at all vacuum levels;
4. Exclusive polycarbonate safety shield protects door glass;
5. Easy-to-clean #304 stainless steel chamber interior with three shelves;
6. Vacuum and air lines constructed with corrosion-resistant stainless steel tubing for optimum chamber cleanliness and long term performance;
7. Three temperature controllers for managing three shelves independently;
8. Built in a large mechanical vacuum pump (9.5CFM) for immediate use;
9. Built in Filter to keep pump from moisture and gases;
10. Four wheels at bottom for movable easily.

Part 2 Vacuum Drying Oven Operation:
1) For using under vacuum, it is necessary to have the vacuum pump;
2) 30 segments temperature profile programmable;
3) Vacuum level displayed on gauges from 0 to 30" Hg;
4) PID precision Digital Power controller controls temperature with a uniformity of +/-5C@ 100C; 25" Hg at center hot zone, 6'x6' center area only) and built-in over temperature protection.
